I gotta go with Grandpa Stinky on this one, if not only for his line in The Penal Zone:
"And as for Harvey over here, he'll be fine. Until we reach a 'You must be this tall to invade this planet' sign!"
"Always expect the best of others... And watch as your hope is crushed like crackers in a fat man's bed. And the fat man is angry. And the fat man has a sledgehammer. And the fat man is yelling 'DIE, CRACKERS, DIE!!'"
